STH-15S SUPERVISED LOUD SPEAKER Description Series STH-15S supervised horn loudspeakers are equipped with a compression driver providing up to 15 Watt RMS power handling capability, superior intelligibility and dispersion to achieve maximum sound projection and penetration. Weather-resistant metal construction and re-entrant acoustic path assure protection against water, humidity, vermin, and corrosion. The mounting bracket allows directional sound dispersion via vertical and horizontal positioning. Provisions are also included for surface or strap mounting to pillars and I-beams. All models include a built-in 25/70/100 V transformer featuring a screw-driver adjustable, 7-position Watt/ impedance selection switch. Wiring terminals are protected with a vandal-resistant adapter cover for control equipment uitilizing cable or conduit. A built-in, 5 mfd capacitor is provided on both models for line supervision. All models meet or exceed the UL Listed standards for audible signal appliances and are capable of operating within an ambient temperature range of 66°C (150°F) to 35°C (-30°F). Models comply with UL Standard 1480 — Speakers for Fire Protective Signaling Systems and California State Fire Marshal (Title 19).
